'4 Claims.

orificesand such accumulations of solid material often clog the jet orifices.

It is the object of the present invention to provide a spray forming wall constructed of parts which are relatively movable in such a manner that accumulations of solid material may be quickly'discharge'd from the'interior of the spray head.

With the above and other objects in view the invention 'may -be said to comprise the spray head as illustratedin the accompanying drawing hereinafter described and particularly set forth in theappended claims, together with such variations and modifications thereof as will be apparent to one skilled in the art to which the invention pertains. Reference should be had to the accompanying drawing forming a part of this specification, in which:

Figure 1 is a side elevation of a spray head embodying the invention with the lower part of the head broken away and shown in axial section;

Fig. 2 is a bottom plan view of the head viewed as indicated at 2-2 in Fig. 1; and

Fig. '3 is a fragmentary transverse section showing the closure disk in tilted position.

In the accompanying drawing the device of the present invention is shown applied to an adjustable spray head of conventional design which comprises an inlet section I, which is internally threaded at its upper end to screw onto a water pipe 2 and which has a ball shaped lower end 3, and a bell shaped body 4 which is adiustably mounted on the ball end of the inlet section. The body 4 has an axial inlet opening 5 at its upper end through which the water is delivered into an enlarged chamber 6, a flat shoulder I being provided around the inlet 5 at the top of the chamber 6. The upper end of the bell shaped body 4 is recessed to receive the ball end 3 of the inlet section and is clamped ,1

spray device associated with the body 4 of the head.

The bottom wall of the chamber 6 is formed by a threaded cap 9 screwed onto the lower end of the body 4. The cap 9 has a large centrally disposed opening ill of a diameter corresponding substantially to that of the chamber 6. The

opening ill is so :formed as to provide a downwardly tapering, substantially conical seat at the margin thereof. A closure disk i2 is formed to fit in the opening Hi, and this disk has the lower portion 13 of its peripheral edge tapered toward the lower face of the disk, tapered portion 13 being preferably concave in transverse section. The upper portion i l of the peripheral edge :of the disk is preferably formed on a taper reverse to that of the portion 13, the tapered surfaces 53 and 'M converging to a seating edge 45 which is adapted to engage the tapered seat i i intermediate the top andbottom thereof. The disk I 2 closes thecpening at the bottom of the head except for spaced orifices Hi which are provided between the margins of the opening l0 and disk '12. As herein shown, the orifices IE5 are formed by spaced notches in the periphery of the disk.

The orifices it are of small diameter so that fine jets of water are discharged at relatively high velocity during operation of the shower head. By pressing upwardly on the under surface of the disk "I2 'at'the center thereof, the disk [2 maybe lifted off the seat H against the pressure of the water within the chamber ii. If the upward pressure be applied at one side of theaxis of the disk, the disk will be tilted laterally to a position such as shown in Fig. 3 of the drawing to permit free flow of water from the chamber 6 over the :face of the disk and over the notched periphery thereof, as well as over the tapering seat H, and such flow of water wil quickly wash away any accumulation of solid material which may have collected within the chamber 6. The'seating edge "35 of the disk is or" greater diameter than the lower nd of the opening Hi, so that the disk cannot be removed downwardly through the opening. The however, is free to tilt in the opening to'a position such as shown in Fig. 3, in which the edge #5 bears upon the seat H at diametrically opposite points and nearly half of the disk projects below the bottom of the spray head. The upper bevel Id of the disk I2 facilitates the pivotal movement of the disk on the seat H and prevents interference between the upper edge of the disk l2 and the lower edge of the seat H when the disk is returned from tilted to normal position.

The disk [2 is preferably backed by a spring within the chamber 6 which serves to normally hold the disk seated in the opening H], but which is yieldable to permit the disk 12 to move upwardly in an axial direction or to tilt laterally in any direction about a transverse axis.

As herein shown, the disk I2 is provided with a central projection I! on its upper side which fits within one or more of the coils at the small end of a conical coil spring I8 within the chamber B. The large upper end of the spring I8 is seated upon the shoulder l at the top of the chamber 6. The spring [8 will readily yield in an axial direction when pressure is applied to the center of the disk and will yield lateraly as illustrated in Fig. 3 when pressure is applied to the bottom of the disk between its center and poriphery. When the disk is tilted to a position such as shown in Fig. 3, the pressure of the spring l8 and of the water flowing through the head will hold the disk in the tilted position until it is returned by pushing upward on the downwardly projecting edge portion of the disk. The beveled upper edge It of the disk permits the downwardly projecting edge of the disk to readily pass back into the opening HI, and when the disk is returned to substantially horizontal position it .snaps into engagement with the seat due to the pressure of the spring 18. The concave edge portion 13 of the disk establishes communication between adjacent jet orifices so that the orifices are not as readily clogged as where the water is discharged through unconnected orifices.

It is apparent that the present invention provides a very simple inexpensive and efficient spray head which can be instantly cleaned whenever any of the jet orifices are clogged by an accumulation of solid material.

It is to be understood that variations and modifications of the specific device herein shown and described for purposes of illustration, may be made without departing from the spirit of the invention.

What We claim is:

1. A shower bath spray head having a chamber with an inlet opening and a bottom wall provided with a single large centrally disposed opening, and a closure disk in said chamber having a marginal seating portion engageable with the bottom wall at the margin of said opening, the marginal seating portions of said disk and opening being formed to provide a circumferential row of jet orifices, said disk being movable upwardly and tiltable laterally in said opening upon application of pressure to the under face thereof to dispose diametrically opposite seating portions of the disk clear of the bottom wall with intermediate seating portions of the disk in engagement with the bottom wall at opposite sides of the opening, whereby pressure upon the engaging seating portions retains the disk in tilted position to permit free flow of water past the disk and through the discharge opening to wash away accumulations of solid material from the interior of the head.

2. A shower bath spray head having a chamber with an inlet opening and a bottom wall provided with a single large centrally disposed opening, a closure disk in said chamber having a marginal seating portion engageable with the bottom wall at the margin of said opening, the marginal seating portions of said disk and opening being formed to provide a circumferential row of jet orifices, and a conical coil spring in said chamber for pressing the disk toward said opening, said spring having its large end engaging the top wall of said chamber and its small end connected to said disk centrally thereof, said disk being movable upwardly and tiltable laterally in saidopening upon application of pressure to the under face thereof to dispose diametrically opposite seating portions of the disk clear of the bottom wall with intermediate seating portions of the disk in engagement with the bottom wall at opposite sides of the opening, whereby pressure upon the engaging seating portions retains the disk in tilted position.

3. A shower bath spray head having a chamber with an inlet opening and a bottom wall provided with a single large centrally disposed opening and a downwardly tapering seat around the opening, and a closure disk having a peripheral edge adapted to engage said seat, the lower portion of said peripheral edge tapering downwardly and the upper portion thereof being reversely tapered, the edge of said disk having spaced notches which with said seat form jet orifices, said disk being movable upwardly and tiltable laterally in said opening upon application of pressure to the under face thereof to dispose diametrically opposite seating portions of the disk clear of the bottom wall with intermediate seating portions of the disk in engagement with the bottom wall at opposite sides of the opening, whereby pressure upon the engaging seating portions retains the disk in tilted position.

4. A shower bath spray head having a chamber with an inlet opening and a bottom wall provided with a single large centrally disposed opening and a downwardly tapering seat around the opening, a closure disk having a peripheral edge adapted to engage said seat, the lower portion of said peripheral edge tapering downwardly and the upper portion thereof being reversely tapered, the edge of said disk having spaced notches which with said seat form jet orifices, and a conical coil spring in said chamber for pressing the disk toward said opening, said spring having its large end engaging the top wall of said chamber and its small end connected to said disk centrally thereof, said disk being movable upwardly and tiltable laterally in said opening upon application of pressure to the under face thereof to dispose diametrically opposite sea-ting portions of the disk clear of the bottom wall with intermediate seating portions of the disk in engagement with the bottom wall at opposite sides of the opening, whereby pressure upon the engaging seating portions retains the disk in tilted position.
